Abstract
Abstract A surgical instrument for joining osseous tissue by V-shaped staples, comprising a bearing stock with a hook carrying a removable dies with depressions for bending staple legs; a staple carrier accomodating a staple magazine, said staple carrier being mounted in the guideways of the bearing stock so as to be moved freely therealong, and a staple ejector mounted in the staple carrier so as to move freely therealong the hook of the bearing stock comprising two component members movable lengthwise relative to each other permitting them to be disposed at different distances from the staple magazine, the dies likewise comprising two portions fixed respective to one of the respective component hook members and serving as bearing surfaces for the respective legs of the staple when the legs are being bent. whereby dimensional variations between osseous tissue being joined is compensated for while the portions and stabilized while being jointed; and the danger from trauma due to protruding sharp staple-edges is minimized.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
324 words
A surgical instrument for joining osseous tissues by staples comprising a back and two legs, comprising: a bearing stock; a hook at one end of said bearing stock, said hook being disposed transverse relative to said bearing stock and comprising two members movable lengthwise relative to each each other; a die consisting of two portions fixed on the different members of said hook for respectively bending a staple leg, a surface of said dies facing the main portion of the bearing stock for contacting osseous tissue to be stapled, depressions formed in said surface of said dies, said depressions engaging and contacting the respective legs of said staples as the same are being bent; a staple carrier freely mounted on said bearing stock for movement therealong; a staple magazine fixed on said staple carrier and having a surface facing said die surfaces, said surface of the staple magazine including portions for contacting osseous tissue to be stapled in opposition to said die surfaces; a staple ejector mounted in said staple carrier and adapted to move therealong, said staple ejector including means for driving out the staples from said magazine as said ejector moves toward said hook and as said staple carrier with said magazine fixed thereon moves along said bearing stock toward said hook whereby one of the bone fragments to be sutured is clamped between said magazine surface and one of said die surfaces, while another bone fragment to be sutured is clamped between said magazine surface and the other said die portion, means connected to one of said hook members carrying said die portions fixed thereon for orienting it at different distances from said staple magazine portions engaging the osseous tissue being sutured, said die portions comprising bearing surfaces for the different legs of the same staple when the legs of said staple are being bent and said staple is driven out by movement of said ejector relative to said staple carrier.
Claim 2
Dependent Claim
324 words
A surgical instrument for joining osseous tissues by staples comprising a back and two legs, comprising: a bearing stock; a hook at one end of said bearing stock, said hook being disposed transverse relative to said bearing stock and comprising two members movable lengthwise relative to each each other; a die consisting of two portions fixed on the different members of said hook for respectively bending a staple leg, a surface of said dies facing the main portion of the bearing stock for contacting osseous tissue to be stapled, depressions formed in said surface of said dies, said depressions engaging and contacting the respective legs of said staples as the same are being bent; a staple carrier freely mounted on said bearing stock for movement therealong; a staple magazine fixed on said staple carrier and having a surface facing said die surfaces, said surface of the staple magazine including portions for contacting osseous tissue to be stapled in opposition to said die surfaces; a staple ejector mounted in said staple carrier and adapted to move therealong, said staple ejector including means for driving out the staples from said magazine as said ejector moves toward said hook and as said staple carrier with said magazine fixed thereon moves along said bearing stock toward said hook whereby one of the bone fragments to be sutured is clamped between said magazine surface and one of said die surfaces, while another bone fragment to be sutured is clamped between said magazine surface and the other said die portion, means connected to one of said hook members carrying said die portions fixed thereon for orienting it at different distances from said staple magazine portions engaging the osseous tissue being sutured, said die portions comprising bearing surfaces for the different legs of the same staple when the legs of said staple are being bent and said staple is driven out by movement of said ejector relative to said staple carrier.
Claim 3
Dependent Claim
24 words

Claim 4
Dependent Claim
51 words
A surgical instrument according to claim 1, in which said hook member includes means replacably mounting the die portions, said die surfaces contacting the osseous tissue being inclined relative to said magazine suRface contacting the osseous tissue for providing the closest possible adherence of said die surfaces to the osseous tissue.
Claim 5
Dependent Claim
21 words
A surgical instrument according to claim 1, in which said die depressions widen from a bottom center portion toward edges thereof.
Claim 6
Dependent Claim
21 words

Claim 8
Dependent Claim
64 words
A surgical instrument according to claim 3, in which said means for replaceably mounting said die portions in said hook comprise slots in said hook members, projections on said die portions removably received in said slots, pins extending through said projections and said slots, and spring plates operatively connected to said pins and said bearing stock for retaining the pins in a locking position.
Claim 9
Dependent Claim
37 words
A surgical instrument according to claim 1, in which said die portions have projections located at the end of said hook and extend toward said magazine and include depressions for respectively receiving one leg of a staple.
